Change that stop delay on line 22 to 0.03 on Facebook and SUDDENLY I'M IN THE FUTURE.

Here's a funny variation that speaks out the counts in different pitches/rates

const speechSynthesis = window.speechSynthesis
const min = 0
const max = 100
const bad = 15 // just a random max to enable 'bad developer' mode

const observer = new MutationObserver(function(mutationsList) {
  const msg = new SpeechSynthesisUtterance()
  const len = mutationsList.length
  
  if (len > bad) {
    msg.text = 'Bad Developer'
  } else {
    const n = len > max ? max : len
    const pitch = ((n - min) / (100 - min)) * 2
    msg.text = len
    msg.rate = 4 - pitch * 4
    msg.pitch = 2 - (pitch * 1.6 * 1.2)
  }

  speechSynthesis.speak(msg)
})

observer.observe(document, {
  attributes: true,
  childList: true,
  subtree: true,
  characterData: true,
})

I honestly didn't like it at first, then I realized how useful it can actually be :) . So I turned it into a basic Chrome extension: https://github.com/R4meau/plink-plonk

I'll be working on it every Sunday (very slow for now) and I'm open for any contributions at any time. Thanks for the head start @tomhicks.

I have moved out the constants into variables, to be able to play with the settings more easily.
I also added a random component. to make it sound less monotonous:

// origin: https://gist.github.com/tomhicks/6cb5e827723c4eaef638bf9f7686d2d8 ,  tomhicks/plink-plonk.js

const audioCtx = new (window.AudioContext || window.webkitAudioContext)()
var delay = 0.03
var freqbase = 600
var freqrnd = 400
const observer = new MutationObserver(function(mutationsList) {
  const oscillator = audioCtx.createOscillator()

  oscillator.connect(audioCtx.destination)
  oscillator.type = "sine"
  oscillator.frequency.setValueAtTime(
    Math.log(mutationsList.length + 5) * (Math.random()*freqrnd + freqbase),
    audioCtx.currentTime,
  )

  oscillator.start()
  oscillator.stop(audioCtx.currentTime + delay)
})

observer.observe(document, {
  attributes: true,
  childList: true,
  subtree: true,
  characterData: true,
})

Then you can play with delay and freq on the fly.

This one randomly decreases/increases tone until it reaches a threshold. Makes it a bit more harmonious:

// origin: https://gist.github.com/tomhicks/6cb5e827723c4eaef638bf9f7686d2d8 ,  tomhicks/plink-plonk.js

const audioCtx = new (window.AudioContext || window.webkitAudioContext)()
var delay = 0.03
// parameters of the random increment/decrement
var freqstart = 600
var freqlow = 400
var freqhigh = 900
var freqspeed = 50
// initial values
var freqinc = 25
var freq = 600

const observer = new MutationObserver(function(mutationsList) {
  const oscillator = audioCtx.createOscillator()

  oscillator.connect(audioCtx.destination)
  oscillator.type = "sine"
  oscillator.frequency.setValueAtTime(
    Math.log(mutationsList.length + 5) * freq,
    audioCtx.currentTime,
  )
  freq += freqinc
  if (freq > freqhigh || freq<freqlow) {
    // reset if we have reached the high or low bound
    freq = freqstart
    freqinc = (Math.random()-0.5)*freqspeed
  }

  oscillator.start()
  oscillator.stop(audioCtx.currentTime + delay)
})

observer.observe(document, {
  attributes: true,
  childList: true,
  subtree: true,
  characterData: true,
})
